Paper Abstract

The behaviour of a dual state quantum dot laser undergoing optical injection is analysed. Depending on the injection current the free-running operation of the slave can be ground state only emission, both ground state and excited state emission or excited state emission only. Complete suppression of the excited state in the dual state lasing regime via sufficiently strong optical injection of the ground state is presented. Injection induced switching between two longitudinal modes of the ground state is also presented in the ground state only regime.
